Studies find global COVID-19 lockdowns have significantly reduced PM2.5 and NO2 pollution, but ozone up

Green Car Congress

MAY 12, 2020

Levels of two major air pollutants have been reduced significantly since lockdowns began in response to the COVID-19 pandemic, but a secondary pollutant—ground-level ozone—has increased in China, according to new research. In addition to nitrogen dioxide, one of the new studies finds PM 2.5 Bauwens et al.

BYD should be accelerating full speed on pure BEVs, but they waste half their effort looking to the past with hybrid technologies - technologies that have been shown in numerous studies to be a major source of toxic emissions, even when charged consistently. Swapping out CO2 for other toxins like ozone and nitrogen oxides is not a solution.

The studies are designed to minimize the effects of extraneous factors and focus on the relationship between the experimental exposure conditions and the biologic response being measured, for example, a temporary change in lung function. The goal is to observe temporary and reversible responses without causing clinical effects.
